A substrate provided thereon, with a film having a large number of fine grooves of a desired pattern is herein disclosed, which comprises a body of substrate and a film of at least one polymerized-condensed or crosslinked organometal compound formed on the substrate and having a large number of fine grooves on the surface and which can be produced by applying a solution containing at least one organometal compound and optionally a thickening agent to the surface of a body of substrate to form a film thereon; then impressing the film with a mold having a large number of fine ridges thereon to form grooves corresponding to the ridges, on the film; or applying the solution to the mold to form such a film and transferring the film to the body of substrate; and then calcining the resulting film having fine grooves to solidify the same. According to the method, an excellent substrate having good durability and optical properties can be produced simply and in a good yield.
